Joint

Abstract

Abstract PURPOSE:To securely hold a bearing portion in a socket without any looseness in a joint by constructing the joint in such a manner that a step portion the opening end side of which is smaller is formed on the circumferential wall of the opening of the socket and a plug is engaged with the step portion at the expanding end of its cylindrical portion to hold the socket. CONSTITUTION:Since the expanding end 23 of the cylindrical portion 21 of a plug 10 abuts to and engaged with the step portion 24 of the opening 2 of a socket 1, disengagement of the plug 19 in A-direction is prevented and a bearing 12 and the ball portion 9 of a pillow ball 6 are held or blocked in the socket 1 without any possibility of looseness in A, B directions or disengagement in the A-direction. In the case of this plug 19, the movement of a plug 18 in A direction is accompanied with the movement in C direction, of the end 23 of the cylindrical portion 21 so the movement in A direction is hard to occur and the looseness and the disengagement of the bearing 12 and the pillow ball 6 may hardly occur.
